Seriously, I did discover the need for that area washer when= I was reviewing the Trutrak drawings.   Thanks to the responses who ca= ught that problem.  I also found 3 more places with similar exposure. &= nbsp; To test what might happen without the washer, I dropped that arm and m= oved the stick.  It locked in a hard left turn when the rod dropped dow= n and got stuck near the actuator.  There would be no cure for that sit= uation in flight.   Therefore, I have decided to spend the $0.06 each o= n the larger washers.

Grayhawk, there was no hose i= nterference but the other end of that rod had a slight rub on the aileron co= ntrol rod so a spacer was added to fix that.   For actuator runaway, th= e ailerons must have a hard stop built in because the actuator can't be move= d more than about 45 degrees off top center which is full stick deflection. &= nbsp; 

My original problem was fixed with the n= ylon shear screws which you can see below.  Two bags at $0.59 each from= Lowes and I believe they are Trutrak approved.
